When looking for a property to develop, or considering extending or refurbishing your home, it’s essential to consider potential risks to ascertain whether it’s a wise investment. You’ll assess the property market, financial goals, and environmental risks. If the property is in a flood zone, prone to bushfires, or subject to other potential hazards, you’ll need to take this into account. So, how do I know if it floods in my area? There are a variety of ways to find out; let’s discuss it.

What Are Flood Risk Areas?

A flood risk area—or flood risk zone—is a location more likely to flood due to heavy rainfall, snowmelt, storm surges, or other conditions leading to water overflow. These areas may span small suburbs or entire watershed regions, making them a key factor when choosing where to develop, buy, or invest.

Which areas are a flood risk:

  • Low-lying areas such as floodplains and coastal regions.
  • Areas near rivers, lakes, and coastal regions.
  • Areas prone to heavy rainfall, snowfall, and tropical cyclones.
  • Areas with limited natural drainage due to urbanisation and infrastructure.
  • Impermeable soil or soil with poor drainage.
  • Levees and dams which influence the natural flow of water.

How To Find Out if Your Area Is Prone to Flooding

There are numerous ways to assess the flood risk in your area before you begin your property development project. These are some that we recommend.

Visit the Bureau of Meteorology (BOM) Website

In Australia, the weather and climate are monitored by the Bureau of Meteorology. In the event of potential flooding, they are the organisation which issues warnings during severe weather events. This information is accessible through their website and social media.

Connect With Your Community

You may have a WhatsApp group or social media forums where various community members pass on vital emergency information and offer valuable insights on past floods and flood-prone areas.

Contact Your Insurance Provider

Insurance companies, offering a wealth of historical and statistical data, can advise you on whether your area is flood-prone, a factor influencing your insurance policy.

Hire a Consultant

You can also hire hydrologists and environmental consultants for a comprehensive flood risk assessment.
